The phenomenon of penetrating discharge between electrodes is caused by collision ionization of gaseous medium under the action of electric field. The breakdown of gas medium is related to many factors, among which the main influencing factors are the acting voltage, the shape of electrode, the nature and state of gas, etc. The common breakdown of gas medium is dc voltage breakdown, power frequency voltage breakdown, impulse voltage breakdown, high pressure electrical breakdown, high vacuum electrical breakdown, negative gas breakdown.
This paper devotes to research and simulation model of gas discharge gap model to solve the numerical calculation method, the analysis of the effect of various parameters in the process of discharge and discharge mechanism of the gas gap, explore the physical laws of gas discharge, promote lingers theory from the direction of half physics to physics research, provide theoretical basis for the design of high voltage insulation equipment. It is of great academic and practical significance to ensure the reliability and economy of insulation design of power grid and improve the operation safety of UHV transmission and transformation equipment.
